The One Piece Wiki covers everything related to One Piece, regardless of whether or not it fits with the canon story. However, editors should know what is and isn't canon and how to treat information depending on its classification.

Canon

The following sources are considered canon and their contents should be used on this wiki. These sources were either created by Eiichiro Oda or by those close to him with his approval. Canon sources include:

• The manga
• The SBS
• Monsters
• Databooks
• Grand Line Times
• One Piece Magazine
• One Piece novel A

Canon Hierarchy

The wiki uses a canon hierarchy in the event of a discrepancy between sources about a piece of information. The hierarchy goes Original Manga <- SBS <- Databooks <- Supplementary materials such as the Grand Line Times. Thus, if a fact presented in a databook conflicts with one in the manga, then the manga information will be used while the databook information will be considered incorrect.

Non-Canon

The following sources are made by people independently of Oda, or by Oda with no intention of fitting with the main story. They do not affect how the wiki documents canon subjects. Non-canon sources include:

• Anything in the anime that was not present in the manga. This is usually referred to as "filler".
• Movies, even those where Oda was involved.
• Color Spreads and Color Walks, as even though Oda draws these himself, the things depicted in them have no bearing on the actual story.
• Video Games
• Novels, with the exception of novel A
• Features and Omakes, eve
• OVAs
• Cross Epoch and other anime crossovers

How Information Should Be Included

All information from canon sources should be included on the wiki, unless it is contradicted by another piece of information from a source higher on the canon hierarchy. Just about any official source is fair game to use on articles about non-canon subjects.

Information about canon subjects from non-canon sources can often also be included, but its non-canon status should be noted and in most cases it should not be given the same weight as canon information. If you are adding information from an anime episode, check to see if it is in the manga. If it isn't, then it's filler and not canon. You can see which chapter an episode corresponds to by opening the "Statistics" section on the episode infobox.

Character Articles

Appearance

Pictures of non-canon outfits can be included in appearance galleries.

Personality

Personality traits that a character shows in non-canon works should not be included, unless we know little to nothing about their personality in the manga.

Abilities and Powers

Non-canon abilities should not be included, unless little to nothing is known about the character's abilities in the manga. The only exceptions are:

• Non-canon fighting techniques should be listed, though in a subsection titled "Non-Canon Techniques".
• If a canon character uses Haki in a non-canon setting, they should get a Haki section, though it should be made clear that their usage of Haki is currently non-canon.

History

History from filler arcs and movies should be included in character histories. However, the subsections should have {{Non-Canon}} and {{Non-Canon|end}} at the beginning and end respectively.

History from other non-canon sources should not be included. Video Game appearances should be noted in the page's Merchandise section. If the character appears in a filler scene in an otherwise canon episode, their actions in said filler should be noted in the "Anime and Manga Differences" section, rather than in their History.

Location Articles

Non-canon parts of a canon location should be included on the article as part of the "Layout and Locations" section with its own subsection, which should be surrounded by the Non-Canon tag.

Canon Subjects with Non-Canon Names

If an unnamed canon subject receives a name from a non-canon source, like the anime, we will use that name for them and give them an article with that name. If they are later given a different name in the manga, SBS, or a databook, we will immediately switch to that name with a mention of the non-canon name in the "Translation and Dub Issues" section.
